JOSEPH A. BUOKWALTER, OF ROYERS FORD, PENNSYLVANIA, ASSIGNOR TO THEBUOKWALTER STOVE COMPANY, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 383,386, dated May 22,18:88.

Application filed June 21, 1887. Serial No. 241,971. (No model.)

To all whom it may concern:

Be it known that I, J osnrn A. BUOKWAL- TER, a citizen of the UnitedStates, residing at Royers Ford, in the county of Montgomery,

State of Pennsylvania, have invented a new and useful Improvement inDust-Flues for Stoves, which improvement is fully set forth in thefollowing specification and accompanying drawings.

My invention consists in providing an openfire stove with a dust-flue,which is easily operated and of inexpensive construction, as will behereinafter fully set forth.

Figure 1 represents'a partial vertical sec- 1 tion and partial sideelevation of a dust-flue for a stove embodying my invention. Fig. 2represents a rear view thereof. Fig. 3 repre sents a horizontal sectionin line 00 00, Fig. 2.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A represents an open-firestove, which is ofusual construction.

B represents a casting, which is of the form of achannel secured to theback Got the body of the stove and extending in a vertical direction,forming with said back a flue, D, whose ends are in communication withthe interior of the stove, respectively above and below the grate, forwhich purpose openings (4 b are formed in the back 0.

WVithin the flue is a valve, E, whose jour nals F are mounted on theside walls of the casting B and having crank F for attachment of a rodor arm, G, which passes along the side of the stove and extends throughthe front wall thereof, so as to be accessible for operating or openingand closing the valve. The front end of the rod has a knob or button, H,forming a handle, the same, when the rod is pushed in to close thevalve, also serving as a stop when the valve is placed in properposition, thus limiting the closing motion of the valve and preventingit from jamming with the walls of the flue D.

When the rod is drawn out the valve is opened, and it is evident thatwhen the fire is raked dust or ashes may now enter the flue through theopening I) and escape therefrom clined upwardly, forming a deflector,which 6o directs the ashes toward and through the opening a in the backof the stove in close proximity to the collar K, said inclined top wallpreventing the ashes from being materially checked in their ascent, itbeing noticed that the upper end of said top wall joins the castingjustbelow said collar K without projecting into the stove.

The casting is prolonged upwardly, and has the pipe-collar K integraltherewith, thus lengthening the casting and strengthening the back (1,which in stoves of this class is generally made of sheet-iron, andavoiding expense of two castings.

Having thus described my invention, what I 5 claim as new, and desire tosecure by Letters Patent, is

A stove having a sheet'iron body with the openings at and bin the backthereof, said openings being respectively above and below the grate ofsaid stove, and provided with a cast-- ing adapted to be secured to saidstove, said casting having a channel forming the passage D between saidopenings a and I), arearwardlyprojecting portion, J, and smoke-flue K,and 8 a damper, E, pivoted in the upper part of said passage D, andadapted to rest on said portion J of the casting when the passage D isopen, said parts being combined, substantially as and for the purposeset forth.
